Widespread testing begins on malaria vaccine
Mothers wait for their children to be vaccinated against malaria at the start of a pilot program at Mitundu Community Hospital, in Lilongwe, Malawi, on April 23, 2019.
With malaria deaths rebounding worldwide, a pilot program testing a new and fiercely debated malaria vaccine began on Tuesday in Malawi. Dr. Katherine O’Brien, the World Health Organization’s director of immunization, called the rollout “a historic moment in the fight against malaria,” and said the testing will soon expand to malarious regions of Ghana and Kenya. But the vaccine, known as RTS,S, or Mosquirix, has been in development for more than 30 years, and it has serious drawbacks that have led some experts to argue that it does not work well enough to spend millions of dollars pursuing.
Malaria kills about 450,000 people a year, most of them young African children. Over the last 15 years, the death rate has been reduced by more than half through extensive, donor-funded efforts to hand out free mosquito nets, spray homes with insecticide and treat people with a new generation of medicines. Nevertheless, deaths have increased again as money has run short, populations have grown, resistance to some new drugs has emerged and mosquitoes have expanded their ranges. Finding new weapons is crucial, experts agree, but making a malaria vaccine has proved challenging in the extreme.
The new vaccine has many weaknesses. It is inconvenient: a child must receive four injections before age 2, sometimes at intervals that do not match the routine vaccine schedules for most other diseases. And it is only partly effective. Testing in more than 10,000 African children from 2009 to 2014 showed that, even after four doses, the vaccine prevented only about 40 percent of detectable malaria infections. The vaccine reduced the occurrence of severe malaria by about 30 percent. It did not protect well against parasite strains that were poor genetic matches, raising a concern that, over time, parasites could evolve resistance to the vaccine as they have to drugs.

How robot carers could be the future for lonely elderly people
Alessandro Di Nuovo
December 6, 2018
The film Robot and Frank imagined a near-future
where robots could do almost everything humans
could. The elderly title character was given a “robot
butler” to help him continue living on his own. The
robot was capable of everything from cooking and
 cleaning to socializing and, it turned out, burglary. This
kind of science fiction may turn out to be remarkably
prescient. As growing numbers of elderly people
require care, researchers believe that robots could be
 one way to address the overwhelming demand. But
even though robots might be able to provide care and,
in some cases, social interaction, many wonder if they
really are the right solution to this uniquely human
 Loneliness and social isolation are already
problems for many seniors and are even linked to
cognitive decline and a higher death rate. With the
population of seniors expected to rise, many worry
that experiences of loneliness will increase, especially
 if access to care is even more limited.
But despite concerns, early studies already show
that social robots – autonomous robots trained to
interact and communicate with humans – really could
address issues of care and social interaction. The
 majority of robotics researchers are largely in favour
of introducing robotic technology on a wider scale
and believe it could reduce loneliness and increase
independence in elderly patients. The Japanese
government even supports introducing robots in
 care homes to solve the country’s ageing population
problem. However, many strongly recommend
carefully balancing the care benefits against the
A class of social robots – mobile robotic
 telepresence systems (MRTs) – have already been
shown to generate positive social interactions with
elderly patients. MRTs are essentially video screens
on wheels raised to head height that can be controlled
remotely using a simple smartphone app. They allow
 relatives and social workers to “visit” elderly people
more often, even if they live in rural or distant places.
Elderly patients don’t need to operate the device,
leaving them free to interact with their social worker
or family. Communication still happens through a
 computer screen, but the robot’s physical presence
mimics face-to-face interaction for elderly people.
Research has shown that people reacted more
positively when talking with someone through an MRT
than through a regular video call or computer avatar –
 especially lonely people. However, MRTs still require
a human operator, which limits the amount of social
interaction seniors can have daily.
To tackle this, developers worldwide have
started creating robot companions programmed with
 advanced artificial intelligence (AI), which can interact
with people on their own. Some examples include
pet-like companion robots, including Aibo and Paro,
which are made by Japanese developers, and MiRo,
which is manufactured in the UK. Other humanoid
 robots, such as the Care-O-bot and Pepper, are able
to provide more complex and comprehensive care.
Though “pet” robots offer limited interaction, they
have proved as effective – or even more so – than
real pets in reducing loneliness for elderly people in
 care homes. Robotic dogs introduced in one UK care
home this year were reported to bring happiness and
comfort to residents.
On the other hand, humanoid robots are already
advanced enough to provide much-needed care to
 elderly people. These robots can pick things up and
move independently, and have a more natural, human
way of interacting, for example, using arm and hand
gestures. More advanced versions have additional
sensors and devices, including touchscreens. Many
 elderly people, finding the touchscreens hard to use,
preferred giving spoken commands to the robot and
reading its response off the screen. But for those with
age-related hearing loss or vision impairment, having
the option to use the touchscreen was indispensable.
 Humanoid robots are still being developed, so their
capabilities are still limited. Moreover, studies of
humanoid robots have mainly focused on evaluating
how well the technology functions without really
considering the social impact. There is also a general
 assumption that it will naturally reduce loneliness.
Though research into social robots is just
beginning, we do know they can provide some solutions
to the challenges mounted by ageing populations, and
could even help reduce social isolation and loneliness.
 At this point, humans are still better in providing care
and social contact to the elderly, but robots might
be able to fill any gaps, especially as technologies
continue to improve. However, before social robots
can be fully integrated into care homes, researchers
 and service providers must address public anxiety
and make it clear that robots are designed to assist
social workers, not replace them. As long as humans
remain in full control to prevent any danger, robots
might well be the future of care.

Lorcaserin, a weight loss drug, has been hailed
as a “holy grail” in the battle against obesity. It works by
suppressing the appetite and increasing satiety but,
unlike many weight loss drugs, scientists found
 lorcaserin did not raise the risk of cardiovascular
problems among at-risk individuals who took part in a
Tam Fry of the U.K. said: “I think there will be
several holy grails, but this is a holy grail and one which
 has been certainly at the back of the mind of a lot of
specialists for a long time.However, Fry cautioned: “But
all of the other things apply—lifestyle change has got
to be root and branch part of this.”
To test the safety of lorcaserin, the researchers
 recruited 12,000 overweight or obese patients. They
randomly assigned the participants a placebo or
lorcaserin. Over a three-year period, the state of their
health was documented.The study revealed that
patients who took lorcaserin lost 4.2 kilograms on
 average (9 pounds), while those on the placebo lost
1.4 kilograms (3 pounds).And participants who took
lorcaserin were at no greater risk of experiencing a
cardiovascular event, like a stroke, when compared with
those who were given the placebo.
 In the past, weight loss drugs have been
discontinued after being found to increase the risk of
heart attacks, strokes, pulmonary hypertension, and
valvular heart disease, the authors emphasized.
